sport / default rider 183 cm
Honda CBR400R vs Kawasaki Ninja 300 ergonomics
Honda CBR400R and Kawasaki Ninja 300 have modeled posture scores within three points for the 183 cm default rider. Treat this as a planning estimate; posture preference, data confidence, and a real test sit still matter.

The modeled scores are within three points, so the result does not distinguish a higher-scoring bike. Treat the result as a planning estimate and compare each bike's geometry confidence before a real test sit.
Rider fit: reaching the ground
The Honda CBR400R lists a 785 mm seat; the Kawasaki Ninja 300 lists 785 mm, within a few millimetres of each other. Seat height is only a first-pass ground-reach input. It does not establish safety or actual foot contact. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change the result.
